Who are Vaillant?

vaillant boilers reviews

Vaillant was founded by a man named Johann Vaillant in 1874, so they have quite the history and pedigree. After over 140 years in business, Vaillant, based in Remscheid Germany, is now a global leader in boiler manufacturing. 

With over 12,000 employees globally, their business goes from strength to strength and is a leader in eco-friendly and sustainable boiler system solutions. 

Being German, you know you can rely on the quality of their engineering and Vaillant are often recognised as the top 3 world boiler manufacturers along with Worcester-Bosch and Viessmann

What boilers do Vaillant make and offer?

Vaillant offers a range of highly efficient and affordable boiler systems. They are well known for their EcoTec plus line of boilers, which are incredibly low noise during full operation.

This means that Vaillant are Quiet Mark accredited and with good reason as these boilers are wonderfully silent.

Here are some of the best selling Vaillant boilers right now that we see our customers asking for time and time again.

Vaillant ecoTEC Pro 28 combi boiler

One of the most popular Vaillant boilers is the Vaillant ecoTEC 28 Pro due to this being the entry-level range from Vaillant, therefore making it slightly cheaper than the other ecoTEC boilers. The Vaillant ecoTEC Pro 28 combi boiler is ideal for small to medium sized homes with 1 bathroom

Vaillant ecoTEC Plus 832 combi boiler

Another excellent boiler from Vaillant is the ecoTEC Plus 832, which is a step up from the entry level Pro model and also with a higher output, meaning it will be more suited to medium sized homes with up to 2 bathrooms. The Vaillant ecoTEC Plus 832 combi boiler is the ideal mid range boiler.

Vaillant ecoFIT Pure 825 combi boiler

If you have a smaller home like a flat or 2 bedroom house and need a boiler to fit in a kitchen cupboard, then the Vaillant ecoFIT Pure 825 is perfect. As the name suggests, the vaillant ecoFit Pure combi is compact and smaller than the other ranges, so when space is at a premium, these boilers are great.

Vaillant ecoFIT Pure 830 combi boiler

If you have a medium sized home but still have little space for a boiler or want to put one in a kitchen cupboard, then the ecoFIT Pure 830 is going to be the best choice for you. The Vaillant ecoFIT Pure 830 gives you that little bit extra power required for homes with up to 2 bathrooms and 3 or 4 bedrooms, all whilst being small enough to be hidden away in tight spaces.

Vaillant Combi Boilers:

For homes and people who have less hot water requirements and are in a smaller home, the best combi boiler range from Vaillant would be a good choice.

Combi boilers heat the water on demand and not in a separate tank and do not require a separate cylinder.

The water pressure in the combi boilers isn’t as high as other systems however so keep this in mind as it relies on how good the water flow into your property is.

Vaillant Heat Only Boilers:

vaillant boilers reviews-heat only

Heat only or conventional boilers are better for larger homes with more than two bathrooms. These types of systems can heat the home , the hot water, and taps at the same time and are perfect for home.

Vaillant heat only (conventional) boilers like other systems, require a cold water tank in the loft or attic and a hot water cylinder usually in the airing cupboard. 

Note that installation time, disruption and cost are all much higher with conventional systems than combi systems as the combi systems have no external tanks.

ecoTEC Plus 43872037534038 kW£1,430

Vaillant System Boilers:

System Boilers have a hot water cylinder similar to conventional boiler systems however they do not need a cold water tank in the attic to work. They take their cold water from the mains supply.

Vaillant systems boilers, and other system boilers are good if you require higher water pressure to more than one tap or shower at once. 

If you have a larger family with baths and showers going on simultaneously, you will know what we’re talking about. There’s nothing worse than having a non-powerful shower dripping out of the showerhead with no pressure.

Vaillant Boiler Warranties review:

Vaillant boiler service (prices)

We know that Vaillant boilers are quite reliable however things can always go wrong with any highly technical piece of equipment.

Compared to other companies, Vaillant offers a competitive warranty option, although not quite as high as other German manufacturers. 

As standard, Vaillant offer 5 year warranties on their boilers, however other brands offer 7,10, and even 15 years of cover with their boilers. 

This means that you may need to pay for supplemental boiler cover to keep your system running at its best level.  You will therefore need to factor this into your new boiler budget. 

What about Vaillant boiler efficiency?

Vaillant boilers are known as efficient systems however now that other manufacturers have upped their game, they are found lagging.

 That is because the average efficiency for Vaillant boilers comes in at 89.8%, whereas comparable boilers from companies such as Viessmann have an astonishing efficiency rating of 98%! 

Also, none of the boilers we looked at from Vaillant have an efficiency rating of A, the closest is B throughout their range.

You will also need to factor this into the cost when you look at a new boiler system as these boilers can be more costly to run. 

Compare Vaillant boilers to other manufacturers

viessmann 200-w

Compare Boiler Quotes may seem like we are repeating like a broken record but we know a good boiler and a great deal when we see it. 

As in our other articles , we always recommend Viessmann Boilers prices when it comes to our reviews and comparisons. 

For example, the Viessmann 200-W. With its ultra reliable stainless steel heat exchanger, up to 98% efficiency and an unbeatable 15 year warranty from Boiler Central, makes it the best buy on the market today.
